Answer 2

Answer:

yes c is the right answer

Explanation:

Li < B < Be < C < N < O < F < Ne.

Ionization energy is the energy required to remove an electron from an atom.

Hence, the more attracted the electrons are to the nucleus, the harder it is to remove the electron. A higher atomic number, then, which corresponds to higher number of protons and electrons, would mean a higher ionization energy - and hence the trend within a period. The further the electrons are from the nucleus, the easier they are to remove from an atom. This explains the trend within a group.  

Note that there are only a few exceptions to this - such as Boron and Beryllium, and Magnesium and Aluminum. These special cases can be explained by looking at the electron configuration. The ionization energy of B is less than that of Be because Boron has a complete 2s orbital. The shielding effect of the electrons in the 2s orbitals make it easier for the electron in the 2p orbital to be more easily removed. In general, however, the trend for the ionization energy holds.
